Hierarchical layered double hydroxide nanocomposites: structure, synthesis and applications

Abstract

Layered double hydroxide (LDH)-based nanocomposites, constructed by interacting LDH nanoparticles with other nanomaterials ( e.g. silica nanoparticles and magnetic nanoparticles) or polymeric molecules ( e.g. proteins), are an emerging yet active area in healthcare, environmental remediation, energy conversion and storage.

Abstract

Layered double hydroxide (LDH)-based nanocomposites, constructed by interacting LDH nanoparticles with other nanomaterials ( e.g. silica nanoparticles and magnetic nanoparticles) or polymeric molecules ( e.g. proteins), are an emerging yet active area in healthcare, environmental remediation, energy conversion and storage. Combining advantages of each component in the structure and functions, hierarchical LDH-based nanocomposites have shown great potential in biomedicine, water purification, and energy storage and conversion. This feature article summarises the recent advances in LDH-based nanocomposites, focusing on their synthesis, structure, and application in drug delivery, bio-imaging, water purification, supercapacitors, and catalysis.
